Method for mixing deer feces and corn straw to prepare organic fertilizer

The invention discloses a method for mixing deer feces and corn straw to prepare organic fertilizer. A fermentation device comprises a fermentation tank (1), a liquid pump (8) refilling system and anair pump (6) oxygen supplementing system; a fermentation chamber (2) is refilled with leachate collected by a liquid storage chamber (5) through a sprayer (9), and an air pump (6) intermittently supplies air through a control switch (7). The ventilation rate is 0.5-0.9 L/min, and ventilation is continuously conducted for 10-18 min per hour; 3-5 min after a liquid pump (8) conducts pumping drainageand refilling, air is supplied for the ventilation of the fermentation tank. Mixed fermented materials in the fermentation room (2) are the deer feces and the corn straw, the initial water content is50-70%, the initial carbon-nitrogen ratio is 28:1-33:1, the crushed length of the straw is less than 3.5 cm, the fermentation temperature is controlled at 50 DEG C or above, and the fermentation timeis 12-15 days.
